 Finally I found a FT232-based RS232 to USB converter. Finally I found a FT232-based RS232 to USB converter.
 This is an expensive cable (but good quality), from an evil company, and it worked. This is an expensive cable (but good quality), from an evil company, and it worked.

 +====== conclusion ======
 +
 +pro:
 +  * fulfils all initial power supply criteria 
 +  * **set output is within accuracy**
 +  * good design, lay out, quality components
 +  * fast first contact response
 +
 +contra:
 +  * output is not switched of completely
 +  * **measured value is up to 0.4 V lower than output voltage**
 +  * second digit after . of voltage is always 0 and not settable (it should not be displayed in this case)
 +  * second digit after . of voltage is always 0 and does not show measured value (the actual measured data is precise enough to show this digit)
 +  * can skip fast knob turns
 +  * USB cable does no fit in port because of the indent
 +  * information in english programming manual missing
 +  * small mistakes in programming manual
 +  * can not be calibrated by end user, and vendor only calibrates if under warranty
 +  * no contact support
